Is B-12 anything like Seafoam? An engine top-end treatment you put in through the intake?

If so, that could explain the massive amounts of smoke - Seafoam or other top-end cleaners will cause a heap of smoke as the deposits cleaned off the walls are burned off.

Namas, the warning about pulling plugs is to allow pressure build up to be relieved - if the cylinder is full of water or any other liquid, then when the piston compresses, it can damage the cylinder or valves due to liquids not being compressible. Taking out the plugs lets the pressure escape through the spark plug hole, and the engine will just pump out the water/cleaner in the cylinders.

You can put the plugs in again once you're sure the cylinder is free of liquid.

If you can turn the engine over through a full rotation using the crank, chances are you're ok - a compression test will tell you for sure, as a bent valve will result in no compression on that cylinder. A low compression result might also happen if the head gasket is blown.

On the smoke - take the car for a drive round the block at 3am - see if the smoke disappears, as it could just be the B-12 stuff burning off. Make sure you top the coolant up before you go round the block - chances are the system will bleed itself and the level will drop anyway after being emptied.

The odds of the head gasket blowing just at the time you started the engine after your TBWP job and washing the ports a bit is very low - I'm betting its just the B-12 stuff burning off.

I got Johns message this morning, my apologies for not getting back to you guys yesterday. I was doing loads of yard work.

Everyone has covered this pretty well so there is really nothing I can add.

Question.

How soon after you sprayed the B12 in to the heads/cylinders was it that you turned the engine over? Did you leave the fluid in there and crank the engine around a lot? Thinking is that if you had the cylinders full of fluid, cranked the engine around by hand or with the starter, you could have done some serious damage, and yes, it might have forced a head gasket out.

Pull the plugs, turn the engine over (have someone do it for you) and watch to see what cylinders the coolant sprays out of.

I started the engine 2 weeks after I cleaned the ports with B-12.
and I am not putting the forum on fault for my problem, sorry if it sounded like that, and sorry if some of you were ofended.
my apology

I am liking this theory:

We're talking about enough coolant to dribble a quart (?) out the exhaust. I assume the engine was not running long enough to warm up and pressurize the cooling system. That does NOT sound like a head gasket.

Remember, the intake was also off for a refresh and the original problem was a toasted/broken breather hose.

Namasgt, I am assuming that the B-12 carb-cleaner was used while the intake was off, is that correct? If you squirted B-12 down the intake with the intake on the car then get some oil in there.

Please post a few pictures of the front of the engine showing the coolant lines. You don't have another engine to compare to, but folks here do. If you don't have a serviceable digi-cam then go buy one, it is an essential tool.

You asked for help here and got a lot of very good advice. You need to follow up on that-- particularly the bit about getting plugs out and finding where the coolant is coming from. The definitive check for a head gasket is a leak-down test, for now it is just a mystery. The common problems are the simple ones, and since all of the hoses were off the top and front of the engine I would start by by checking coolant hoses.

Please post what you find, and please post some pic's.

A small head gasket leak will not be found by a leakdown test.

One as big as the op is talking about, yes it will find that.

I have repaired hundreds of blown head gaskets, and have never seen one bad enough to have coolant dripping out of the exhaust.

There really is not 100% positive way to check for a blown head gasket, the small ones are the ones that will give the most issues trying to find.

I have my doubts that the OP had a head gasket issue when this started, but I suspect he has some bigger issues now if he used the starter motor to turn the engine with any liquids in the chambers.

The best way I have found is with a double chamber, chemical tester, which checks for the presence of exhaust gasses in the cooling system.

They are cheap, I think I paid about 50 bucks for the last one I bought, you can get them from any of the pro tool guys like Mac or Snap-On.

I have also used a four gas analyzer to test for them, but that is not something most guys are going to have access to.

okay
I took all plugs out
plug # 8 had droplets of water on it, the other ones seemed fine.
I used an Aquarium hose and send it down in each plug hole and siphoned from the other side.
only piston # 8 had excessive GREEN coolant.
after a while the # 8 plug hole start getting flooded with coolant and purring out.
I cranked the engine and the coolant just shoot out of the piston on the neighbors’ car.
Now smoke was coming out of both exhaust .
Could it be that one of the pistons on the other side is cracked so coolant is going to the oil pan?
Now Im debating if I should rebuilt the engine if noting else than the gasket is damaged or just sell the car.
This was bit of an adventure for me but it looks like the ending is bad.

so that’s exactly what happen to me except I did not drive the car. some B-12 might have been left in there in those 2 weeks then when i cranked it 2 days ago it blew the gasket ( I still think the B-12 should have been gone by 2 weeks) when I started the engine for the first time it idled at 1000 RPM and it was roaring fine except the injector sounds and the vacuum line sounds but no banging coming from the engine block.
I dont know maybe I really messed up or It could just be the head gasket.
thanks

If you are allowed at your location, yank the cam cover, the cams and just pull the head. (our cam tools are out on loan sorry) and go from there. It's not all that hard and I'm sure those close to you can give a hand. If none of the valves are bent, you should be good to go with a cheap fix of that gasket, oil change or 2. It can be done with the engine in the car.

Ohhhh.... that's bad. HOPEFULLY, it's just the head gasket.

Have you checked the oil for a milkshake? (i.e. antifreeze in the oil)
